Slot coupled patch antenna design

On the Use of Slots in the Design of Patch Antennas

A-SLOTTED RECTENGULAR MICROSTRIP PATCH ANTENNA - ijaiem.org reduced size wide band microstrip antenna; the design idea was taken from broadband antennas to make the antenna work in a large band of frequencies, rectangular patch antenna was chosen. There are many methods to reduce the size of the patch i.e. shorting wall, shorting pin, slot cutting etc. [4, 5]. The shorting microstrip antenna is a ... Effect of the Different Shapes: Aperture Coupled Microstrip ... Abstract: The paper reviews the effect of the different shapes on the aperture coupled microstrip slot antenna. Aperture coupled microstrip slot antenna couples the patch antenna with microstripline through an aperture. One effective way to increase the impedance band-width is to change the patch shape, feed shape and the slot shape. Design, Implementation and Experimental Comparison between ... Fig. 9. Constructed dual port,dual polarized slot coupled patch antenna The simulated and measured S11,S22 and S12 results for proposed and implemented dual polarized slot coupled antenna are shown in Fig.10.The quarter wave microstrip fed (port 1) has 50MHz and slot coupled port (port2) has 100MHz input 10dB bandwidth. Broadband Capacitive Coupled Microstrip Antenna with I-shape ...

In this work, we focus on the design of a X-band dual-polarized antenna which will be ... patch antenna with four capacitively coupled feeds is presented which can achieve an ... (0.9 × 0.9 × 0.23 at 3 GHz). In [18], a dual-polarized slot antenna.

The Q of this valley can be adjusted by varying the substrate thicknesses, slot width or patch width. ...

Defense Technical Information Center Compilation Part Notice ... The simulated return loss for this CPW slot-coupled patch antenna design is shown in Fig. 2. In HFSS, an CPW slot width (w) 50 pin excellent resonance at -30.2 GHz was obtained after the patch antenna dimensions and CPW feedline Slot dimensions 1078 x 124 pm
